| Overview | Thiết kế đơn giản; cả hai ứng dụng cùng nguyên lý vào lạnh – ra nóng. |

| Body 2 | Làm nóng khí và làm nóng nước (có ống nước uốn khúc). |
The given diagrams illustrate the structure of a solar panel and two ways in which it can be used: to heat air and to heat water.
Overall, the panel has a simple design, and in both applications the process works on the same principle, commencing with a cool substance entering the box and culminating in it leaving at a higher temperature after absorbing heat from the sun.
In terms of the first diagram, the solar panel is a rectangular box with a transparent top fitted over it. An inlet is attached to one side of the box and an outlet to the opposite side.
Turning to the remaining two diagrams, when the panel is used to heat air, sun rays pass through the transparent top and are trapped as heat inside the box. Cool air is drawn in through the inlet, warmed and released as warm air through the outlet. Similarly, when heating water, the panel contains a winding water pipe connecting the inlet to the outlet. Cool water flows into this pipe, is heated by the sun's energy as it travels through the box, and emerges as warm water.
